摘要: 2005~2007年共6次采集了三江平原主要河流和水田集中分布区的地下水水样,分析可溶性铁含量。结果显示:地下水中Fe2+含量普遍高于Fe3+;可溶性铁含量变化于0.03~21.00 mg/L,平均为5.48 mg/L,最大值出现在夏汛期。江河水中可溶性铁的主要形态是Fe3+;可溶性铁含量的变化范围是0.04~2.05 mg/L,平均为0.42 mg/L,峰值也出现在夏汛期;沼泽性河流中可溶性铁含量高于非沼泽性河流。松花江可溶性铁输出通量为240×105kg/a,黑龙江为200×105kg/a,乌苏里江为70×105kg/a。

Abstract: River and groundwater samples were collected from Sanjiang Plain in Northeast China in middle Heilong River watershed from 2005 to 2007 to study the temporal and spatial distribution of water-soluble ionic iron(WSIFe,including Fe2+ and Fe3+).It can be concluded that the concentration of Fe2+ is generally higher than Fe3+ in the groundwater.The concentration of WSIFe ranged from 0.03 to 21.00 mg/L,with an average of 5.48 mg/L,and fluctuated with the groundwater level.In the river water samples,WSIFe presented in form of Fe3+,and the concentration of WSIFe ranged from 0.04 to 2.05 mg/L,with an average of 0.42 mg/L.The content reached a peak in the flood season.The concentration of WSIFe in the rivers derived from marsh is much higher compared to the river derived from forest areas.The WSIFe flux of upper-middle Heilong River,lower Songhua River and lower Wussuri River was 200?105 kg/yr,240?105 kg/yr and 70?105 kg/yr,respectively.
